Patent DE-2714726-A1 (DE)
Title: Self steering system for yacht - has mechanical feedback from rudder to vane which prevents over correction
Inventor: SCHWING FRIEDRICH DIPL ING
IPC: B63H25/04
Filed: 1977-04-01
Abstract: The self-steering gear for a yacht incorporates feedback from the rudder to the vane, thus eliminating over-correction. The vane rotates relative to its base about a vertical axis. The base has a vertically pivoted mounting on the stern of the yacht and is connected by a mechanical or hydraulic linkage to the rudder mechanism. Deflection of the vane actuates a double-acting hydraulic master cylinder mounted on the vane base. The master cylinder is connected to a slave cylinder which operates the rudder. Rudder movement resulting from vane deflection retores the vane to a neutral setting by means of the feedback linkage.

Title: Lifting crane for ingot holding grab - utilises grab mechanism weight for increasing grab holding horizontal force
Inventor: KROPIK ERNST
IPC: B66C17/12
Filed: 1977-11-18
Abstract: The crane with grab is used as furnace charging crane or ingot transporter. The grab is held on a travelling trolley with lifting and lowering system.

Title: Coin tester using electronic probe - selects mechanical sorter for predicted coin type and examines dimensions of coins
IPC: G07D5/00
Filed: 1978-03-25
Abstract: The coin testing appts. tests each coin testing appts. tests each coin electronically by means of a probe (4).

Title: Superheterodyne receiver suppressing signal distortions - detects reference carrier to sideband ratio to block auxiliary frequency control
Inventor: HENZE WERNER ING GRAD
IPC: H03D1/22
Filed: 1978-11-15
Abstract: The superheterodyne receiver has a synchronous demodulator for amplitude modulated signals transmitted with a reference carrier and a circuit to generate an auxiliary carrier signal from the reference signal. The modulated intermediate frequency signal is demodulated in the product demodulator using the auxiliary carrier frequency from the quartz oscillator. The limited reference carrier is compared in phase and frequency in the comparator. Its output corrects the auxiliary carrier oscillator phase and frequency. If the side band amplitude becomes greater than the reference carrier amplitude the signal input and the clock input of the D-flip-flop no longer match and its output pulses trigger the monoflop which switches to its unstable state and blocks the oscillator circuit. This suppresses reference carrier interference.
